Inverse Address Resolution Protocol

<networking, protocol> (InARP) Additions to ARP typically
used for Frame Relay. [Any other examples of its use?]
Frame Relay stations route frames of a higher level
protocol between LANs, across a Permanent Virtual Circuit.
These stations are identified by their Data Link Control Identifier (DLCI), equivalent to an Ethernet address in a
InARP allows a station to determine a protocol address (e.g.
IP address) from a DLCI. This is useful if a new virtual circuit becomes available. Signalling messages announce its
DLCI, but without the corresponding protocol address it is
unusable: no frames can be routed to it.
Reverse ARP (RARP) performs a similar task on an Ethernet
LAN, however RARP answers the question "What is my IP
Address?" whereas InARP answers the question "What is your
